Prolongation of Islet Allograft Survival Following in Vitro Culture (24°C) and a Single Injection of ALS

Abstract

Isolated rat islets remain morphologically and functionally intact during a 7-day period of in vitro culture at 24 degrees C. In vitro culture of islets at 24 degrees C for 7 days prior to transplantation, in conjunction with a single injection of antiserum to lymphocytes into the diabetic recipient, results in islet allograft survival of 100 days when the islets are transplanted across a major histocompatibility barrier.
